Question 1

What force continues to drive blood through the vasculature during ventricular diastole?

Accepted Answer

A)  ventricular contraction forces blood into the vasculature during ventricular diastole. 
B)  the elastic recoil of the stretched arterial walls provides the force to continue blood flow in the remaining vascular system during ventricular diastole. 
C)  sympathetic stimulation produces arterial vasoconstriction, which drives the blood forward into the arterioles during ventricular diastole. 
D)  skeletal muscle contraction squeezes the blood forward from the arteries during ventricular diastole. 
E)  respiratory movements produce pressure changes in the chest, which establishes a pressure gradient that drives blood forward from the arteries into the microcirculation.
